Could the 21-cm absorption be explained by the dark matter suggested by $$^8$$ 8 Be transitions?
Abstract The stronger than expected 21-cm absorption was observed by EDGES recently, and another anomaly of $$^8$$ 8 Be transitions would be signatures of new interactions. These two issues may be related to each other, e.g., pseudoscalar A mediated fermionic millicharged dark matter (DM) and the 21...
